I am a senior web developer with over 8 years of experiences. With these days, have built many front-end and backend websites in Node.js, PHP, Javascript and its frameworks with cross-browser, pixel perfect and responsive. Now, I am focusing on Blockchain and Cryptocurrency technology. I had created some coins by forking from Bitcoin, Monero, Dash and so on, and created their wallet, exchange and mining software, too. I have good experiences and skills with Ethereum, Solidy and Smart contract, too.
